A uniform rod of length πR/ 2 is bent in the shape of a quadrant of radius R . The rod has one end on the ground and the other leaning against a frictionless wall, as shown in the figure. Which of the following is the force A exerted by the wall on the quadrant for the system to be in equilibrium?
1
A = 0.293 W
2
A = W
3
A = 0.5 W
4
A = 0.707 W
